I am getting the same error, but it appears when the image "highway.png" is changed for another one.
I = imread('highway.png');
I = imresize(I,inputSize(1:2));
[bboxes,scores] = detect(detector,I);

Yonathan Zarkovian, I think the error shows up when an image is not what the algorithm is waiting for. I uploaded different kind of images and only similar images to the dataset worked.
